Resumo: |
It is important that the machining processes are continually improved in order to provide competitive advantages and economic conditions for manufacturing companies. A very used manufacturing process, mainly because it is one of the few that allow obtaining small diameter internal thread, is the thread tapping with thread cutting taps. As such, thread tapping is one of the last process to be carried out and any failure can influence in production costs. One way to reduce costs is by increasing the useful life of the thread tap through the use of surface treatments, coatings or cutting fluids. Therefore, the main objective of this work is to evaluate the performance of the application of a dry impregnated lubrication on the surface of thread taps, with a focus on conventional tapping process improvement concerning tool useful life and, consequently, costs reduction. For this purpose, tests in the tapping process were performed using high speed steel taps in two conditions, i.e., treated or not with a dry impregnated lubrication. The results obtained allow to conclude that the procedure employed was appropriate, because it increased the tool useful life, reduced the tool wear, and maintained the thread quality, promoting a reduction in manufacturing costs. |
